SPEGIFIGA'IION formingpart of Letters Patent-No, 622,498, dated April l,1899.

llpplioetioniiled August 31, 1898.- Berlsl No. 689,936. N modeL) To allwhom it may concern.-

Be it known that l, Cnms'rmu KRAMER, a citizen of 'Germany, residing atNew York, borough of Bronx, State of New York, have in vented certainnew and useful Improvements in Alarm Attachments for"-lower-Looms, ofwhich the following is a specification.

This invention is intended to'supply an alarm attachment forpower-looms, so that whenever one of the shafts of the same drops animmediate alarm is given, so that the attendant can stop the loom andlook for the cause of the interruption and repair the defeet before anyimperfect goods have been made, which would naturally be the case if theloom continues, and thereby save labor and material. i

The invention consists of 'an alarmattachment for power-loomswhich isactuated in case any one of the shafts is dropped, said attachmentconsisting of one or more springwire frames located transversely belowsaid shafts and composed of a stationary guide portion having eyes and ayielding spring portion that is depressed so as to close an electriccircuit whenever one of the shafts drops for one reason or another, soasto ring an alarm and call thereby the attention of the attendant to thedefect, so as to stop the loom.

The invention consists, secondly, of the special construction of thealarm attachment, which will be fully described hereinafter, and finallypointed out in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of aribbon-loom with my improved alarm attachment shown in position thereon,and Fig. 2 is a perspective view of oneof the attachments and theelectric conducting-wires arranged in connection therewith.

Similar letters of reference indicate corresponding parts.

' Referring to thcdrawings, A represents the supporting'frame, and B theshafts, of a ribbon-loom of any approved construction. On

the longitudinal beams a of the frame A are arranged below the shafts 13one or more wire alarm attachments C, which are formed of two uprightwires 01, having horizontal guide-eyes d and a V-shaped wire (1 that isattached at one end to the longitudinal beams of the supactuated by thesame.

porting-frame A. The free ends of the V- shaped wires (1 are, connectedtransversely below said eyes d by a wire (1" and in addition thereto bya transverse stiffening-wire d" at the apex of the V-shapedwires, asshown in Fig. 2. The V-shaped wire frame has a certain spring action, sothat if one of the shafts should become disconnected and drop down onthe transverse wire of the attachment the latter will move in theguide-eyes in downward direction, bending on the fastening ends untilthe lower transverse portion-comes in contact with the electricconduetingwires 0 c, that run along the face of the longitudinal beamson and form connection with the poles of a battery E, so that anelectric alarm l) is The battery may be located at any suitable positionnear the loom,

so as to be called into action as soon as the circuit is closed by thelower end of the trans-- verse lower portion of the wire f ramc, asshown in dotted lines in l igi 2.

The alarm attachment enables the attendant of the power-loom toimmediately repair any broken cord or other defect connected with theoperation of the shafts without waste of time and material h' etoforcconnected with such accidents. Tl.

cell is rung as soon, as any one of the shafts falls down, for thereason that the-alarm attachment is lowered and placed in contact withthe electric conducting-wires of the circuit, so that the alarm is rungand the attention of the attendant drawn to the fact that the shafts ofthe loomare not in good working order.

He then knows that he has to immediately stop the loom and repair the dofeet before further dam age occurs. He is thereby enabled to saveconsiderable in time and material, as the imporfect part of the goods,which would naturally have been made if the loom had continued 4 runningwith one or more shafts out of: place,

would have to be undone again, the material 1 being wasted and time lostby this operation.

Having thus described my invention, I claim as new and desire to secureby Letters 1atcnt- 1. The combination, with the frame of a power-loom,and the shafts of the same, of a wire alarm attachm out extendingtransversely across thc'framc of the loom below said shafts,

and an electric circuit closed by saidalarni' attachment when one of theshaftsdrops on the same, substantially as set forth.

2. An alarm attachment for power-looms consisting of a V-shaped wireframe located below the shafts and attached at one end to thesupporting-frame of the -l00m and pro-v vided with a transverseconnecting-wire at' the ends of its V-shaped reds, guide-eyes for thefree ends of said V-shaped rods, and an electric circuit closed by. thedropping of a. shaft upon said wiroframe, subst-antia'ilyas set forth;

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
